When P0883R2 was initially implemented in D103769 #pragma clang deprecated didn't exist yet.
We also forgot to cleanup usages in libc++ itself.
This takes care of both.

This removes the `format_args_t` from `<format>` and adjusts the type of
the `format_args` for the `vformat_to` overloads.
The `format_context` uses a `back_insert_iterator<string>` therefore the
new `output_iterator` function uses a `string` as its temporary storage
buffer. This isn't ideal. The next patches in this series will improve
this. These improvements make it easy to also improve `format_to_n` and
`formatted_size`.
This addresses P2216 `6. Binary size`.
P2216 `5. Compile-time checks` are not part of this change.
Implements parts of:
- P2216 std::format improvements

Several of our C++20 and C++2b papers were missing the actual revision
number that was voted in to the Standard. The revision number is quite
important because in a few cases, a paper has a revision *after* the
one that is voted into the Standard, which isn't voted into the Standard.
Hence, if we simply followed the wg21.link blindly and implemented that,
we'd end up implementing the latest revision of the paper, which might
not have been voted.
As a fly-by fix, I found out that P1664 had been withdrawn from the
straw polls and had never been voted into the Standard. This commit
removes that entry from our list.

Implement P1391 (https://wg21.link/p1391) which allows
`std::string_view` to be constructible from any contiguous range of
characters.
Note that a different paper (http://wg21.link/P1989) handles the generic
range constructor for `std::string_view`.
